1 This is the only document in the table that is not an enforceable multilateral treaty. It is included because it marks the beginning of substantial international cooperation on drug control.

2 China, the Netherlands, and the U.S. implemented the Convention in 1915 (Honduras and Norway followed suit later that year). It did not come into force globally until it was incorporated into the Treaty of Versailles in 1919.

3 As amended by the Protocol signed at Lake Success, New York, on 11 December 1946.
